function lib_demotest(&$ctag,&$refObj)
{
global $dsql,$envs;
//属性处理
$attlist="row|12,titlelen|24";
FillAttsDefault($ctag->CAttribute->Items,$attlist);
extract($ctag->CAttribute->Items, EXTR_SKIP);
$revalue = '';
$innertext = $ctag->GetInnerText();
$ctp = new DedeTagParse();
$ctp->SetNameSpace('field', '[', ']');
$sql = "SELECT * FROM dede_archives WHERE 1=1 limit 0, $row";
$dsql->Execute('me',$sql);
while($rs = $dsql->GetArray('me'))
{
//根据属性处理查询变量
$rs['title'] = cn_substr($rs['title'], $titlelen);
//获取底层模板
$ctp->LoadSource($innertext);
foreach($ctp->CTags as $tagid=>$ctag) {
if(!empty($rs[strtolower($ctag->GetName())])) {
$ctp->Assign($tagid,$rs[$ctag->GetName()]);
}
}
//根据底层模板及查询变量得到处理结果
$revalue .= $ctp->GetResult();
}
return $revalue;
}
在include/taglib/建一个demotest.lib.php 文件
然在需要的模板文件里加入
{dede:demotest row='10' titlelen='36'}
[field:title/]
{/dede:demotest}
